If you are asking what type of video card is installed in your system, it could be any one of the many video cards that Dell offered as options on this system. What is the service tag of your system? You can find that on a white sticker on the back of the system and on the top of the left side panel.
The service tag that you have given is not a valid service tag here in the US. Perhaps the first number is really a letter -- Perhaps a letter "G" instead of a number "6". I do see from your post, that you have found out what type of video card is installed along with much more information about your system.
The motherboard is an Intel Motherboard. It has an Intel 815e chipset. Basic system specs can be found at this link:
If your system has an integrated network card, it is an Intel 82562 10/100 card. I cannot identify any other peripherals in your computer since the service tag that you gave is not a valid service tag here in the US. If you want to know more about what is inside your computer, you may need to remove the cards so that you can research more information about them.
